Application of S-RC Hybrid Structure in Indoor Substation of Large Wind Farms Transmission Through VSC HVDC
-
Abstract
Through 863 large wind farms transmission using VSC HVDC technique project, steel-reinforcement concrete hybrid structure was introduced to be used in the indoor converter station structure design, according to its both advantage of steel structure and reinforced concrete structure. This paper gave the process how to select the structural form, the structure characteristics and its technology advantages; the structure integral calculation and key component design calculation results were shown in the design; after comparing with the whole steel structure form both in technical and economic aspect, prospects of using steel-reinforcement concrete hybrid structure in indoor substations and its key matters in design was discussed, which will be a good reference for the design of steel-reinforcement concrete hybrid structure in indoor substation in the future.
